Flash with the possibility of gravitational waves

In 1887, Lewis Swift managed to notice a bright cloud or nebula distant 2.2 billion light years away. Now we know that this is the galaxy IC 10, filled with interesting stellar activity.

This object is observed by the most powerful telescopes and the Chandra X-ray Observatory. We managed to find a lot of star pairs, which once are able to become a source of gravitational waves.

Looking at Chandra’s observations of IC 10 over the past ten years, scientists have been able to find more than 12 black holes and neutron stars fueled from their smaller neighbors. Such systems are called X-ray double because they create a huge amount of X-rays.

When a massive satellite consumes all the fuel, it passes through a catastrophic collapse and explodes like a supernova. After itself leaves a neutron star or a black hole. As a result, we see a pair: two black holes, neutron stars, or a neutron star and a black hole. If the distance between them is small, then we will catch gravitational waves. Their orbit will shrink until they become a single object. Over the past two years, LIGO has found three pairs of black holes. Such star flares represent excellent areas for searching for X-ray neighbors. The more massive the pair, the faster it will approach the final stage. But a new snapshot of the IC 10 combined Chandra data (blue) and optical observations (green, red and blue).

Young stars came to a suitable age for contact with massive objects. If the systems were even younger, there would not be enough time to transform into a supernova. Chandra Observatory has found 110 sources of X-rays in the galaxy. Approximately 40 of them can be observed in the usual review, and 16 have blue supergiants.
